Hope you weren’t using at below waist height!Wrecked a large cup brush on a 9" grinder.... brush 4500rpm... 9" was 9000.... lasted long enough for the job, and let go slowly.. sort of unpeeled the large rivet in the middle, and went loose.. luckily spotted it before it went really wrong
Only then did i notice the small print of the speed rating
